CompTIA Network+ (N10-008) — Question 32

Which of the following TCP ports is used by the Windows OS for file sharing?

Answer options

• A. 53
• B. 389
• C. 445
• D. 1433

Correct answer: C

Explanation

The correct answer is C, as TCP port 445 is specifically used by Windows for file sharing via SMB (Server Message Block). The other options are not associated with file sharing; for example, port 53 is used for DNS, port 389 is for LDAP, and port 1433 is for Microsoft SQL Server.
